Tennis star's growing business is part of her plan to promote healthy living and fitness.

The 32-year-old tennis superstar, who recently claimed her fifth Wimbledon doubles title with sister Serena, opened a second Jamba Juice location outside Washington, D.C., earlier this month. She launched her first store in Bethesda, Md., last year.

“My goal is to help inspire our nation’s youth to become more active and to make better dietary choices. As a recognized healthy, active lifestyle brand that offers simple menu solutions for eating right while engaging in healthy activities, Jamba Juice is a perfect fit to help me in that endeavor. I am excited to be opening stores this year and proud to be a part of the Jamba Juice organization,” she said in 2011.

Williams last year revealed that she is suffering from Sjogren's Syndrome, an autoimmune disease that results in lower energy levels, fatigue and joint pain. As a result, she switched to a raw vegan diet, telling "CBS This Morning" that the change has "made a big difference."

"I'm not perfect, so I forgive myself when I make mistakes and I do a lot of juicing as well, a lot of wheat grass shots ... lots of fresh juices and things like that," she said.

Jamba Juice, which has a focus on healthy products and plentiful vegan and vegetarian options, seems like a natural fit for Venus. In fact, she plans to open five more stores in the D.C. area over the next five years.

“I am thrilled to be in DC to celebrate the opening of my newest store," she said in a statement. "For more than 10 years, my family and I have worked closely with the District government and various community leaders to offer adults and children greater opportunities through education and sports. My partnership with Jamba Juice is an extension of that commitment in the fight against obesity and to promote a healthy active lifestyle.”
